Those tubes aren't hard plastic and this isn't made by Asetek. It seems Fractal actually designed and got manufactured their own cooler. The tubes are a soft flexible material with a anti-kinking spring like surround that you can remove. Fractal has been holding off selling it in the USA because of Asetek suing over anyone making water coolers. They're claiming patent infringement over anything that's a maintenance free cooling system with a pump and radiator connected by hoses. Total BS.Bah, you'd think asetek would have ditched that tiny hard tubing by now.
